This invention relates to devices for Securing the cables from which street lamps 4are hung to such supports as posts, to prevent unauthorized persons from meddling with such cables.

p It is now the common practice to support street lamps from posts and similar supports by means of cables which run over vsheaves carried by thesupports. A street lamp is attached to one end of such a cable to be raised or lowered thereby and the other end of the cable is attached to the post or other support. To lower the lamp, it is necessary to release the last mentioned or oper- 5 ating end of the cable from its support. Mis- 0 ating ends of such cables from their supportschievous boys and other unauthorized persons have caused considerable annoyance and exy pense to power companies and other owners of such street'lamps by releasing the operand allowing the lamps to drop to lowered position.

It is the purpose of this invention to provide novel and improved means for attaching the operating end of such a cable as above described to a support, such as a post, to prevent unauthorized persons from releasing the said end of the cable from such a support but permitting authorized personsrto, at times, release the said end of the cable from the suport. p To this end, generally stated, the invention consists in the novel parts and novel combinations of parts hereinafter defined in the claims and described in the following speciiication, made in connection with the accompanying drawing, wherein like reference characters refer t-o the same or similar parts throughout the various views and, in which,

and showing the device applied to a post, certain of the parts being shown in one position in full lines and in another position in dotted lines; and

Figf is a view illustratng a key that may be used in connection with the device.

Referring to the drawing, there is illustrated a lamp post 6 having secured adjacent its upper end thereto an outwardly projecting arm 7 supported by a cable 8. A sheave 9 is mounted on post 6 adjacent arm 7, while another sheave 10 is mounted at the outer end of the arm. A-eable 11 runs over the two sheaves 9 and 10 and the upper end of this cable is connected to a street lamp 12. The lower end of the cable 11 is adapted to be releasably attached as to the post 6 and by releasing this lower end of the cable Vfrom the post, it will be seen that the lamp 12 may be lowered for inspection or repair, whereupon the lamp can be again raised to its operative position.

To releasably secure the lower end of a cable, such as the cable 11, to a support such as the post 6, I provide in accordance with the invention, a block 13 of greater length than width. This block 13 has a rectangular boss 13a: which yprojects outwardly beyond the main portion of the outer surface of the block and a tapped opening 13b is formed in the block and this tapped opening extends centrally through the boss 13a. Block 13 is securely fixed in place on post 6 usually five or sixV feet from the ground, as by means of spikes 14 which run through upper and lower openings in the block 13,-and have heads, the outer surfaces of which are disposed inwardly from the outer surface of boss 13a. A plate 15 of a width approximating the greatest width of block 13 and of considerably greater length than the block 13 overlies this block 13 `and has an elongated aperture 15a therein within which boss 13a and the heads of spikes 14 fit. When the plate 15 overlies the block 13, the sides of the boss 13a strike the plate to prevent turning movement of` the plate relative to the block. Plate 15 has inwardlyv extending flanges at its sides and upper end above block 13l to form a housing 155 having an open inner side. A cable opening 15o is-cut through the end flange of housingV 15b to kpermit insertion of the lower end of cable 11 within the housing. The lower end of the cable 11 is securely anchored within the housing by loopingthe same about a stud 16 carrying a washer 17 and screw threaded within the housing 15b. An opening 15d is provided in the lower end of plate 15 to receive a hook (not illustrated). A bar' 18 of a length corresponding to thel length of the aperture 15a and having a central outwardly projecting apertured and recessed boss, bears against the outer surface of the boss 13a and normally projects transversely across plate 15. This bar 18 has inturned lugs 18a at its two ends between which the plate 15 will be received when the bar is extended transversely of the plate rand is disposed flush Vagainst the outer surface of the boss 13a. A

stud 19 projects through the aperture ofthe bar 18 and is screw threaded within the tapped opening 13b of block 13 and this stud has an enlarged cylindrical head which normally fits within the recess of the boss of bar 18. A polygonal-shaped socket 19a is provided in the outer surface of the stud 19 to receive one end of a key 20 also of polygonalshape in cross section.

Under normal circumstances tohold the lower end of the cable 11 securely attached to the post 6 and to prevent detachment of the same from the post by unauthorized persons, the various parts will be positioned as shown inv Figs. 1, 2, 3 and in full ylines Fig.'

4. When the parts are in this position, the post 6 closes the rear side of the housing 15b and no access may be had to the lower end of the cable 11. The lugs 18a of the bar 18, together with the boss 13a prevent removal of the plate 15 from its position overlying the block 13 and also prevent relative rotation between the three parts 13, 15 and 18.v

As the heads of the spikes 14 are disposed within the aperture 15a of the plate 15, ac

cess to the spikes for removal of the same cannot be had. As the cylindrical head of the stud 19 fits tightly within the recess of the boss of bar 18, it will be impossible to loosen this stud unless the peculiar shaped key 20 is employed. It is thus `practically impossible for unauthorized persons to release the lower end of the cable 11 from the post 6.

When authorized persons desire to lower the lamp 12 for repair, a key such as the key 20, rwill be first inserted within the socket 19a of stud 19 whereupon the stud. will be unscrewed for a short distance or until the inner ends of the lugs 18a vmay be swungA line position shown in Fig. 4 and as this oecurs, bar 18 will be carried through the aperture 15a of the plate. kA hook to which a rope is attached may now be connected with the platel 15 through the hook opening 15d, whereupon the lamp 12 may be lowered for adjustment, inspection or repair. It will be j seen that the lower end of the cable may be 1.
